Use appropriate existing remittance advice reason and remark codes at the line level to express the specific reason for
denying payment for PT/INR:
Remittance Advice Remark Code N386, “This decision was based on a National Coverage Determination (NCD). An
NCD provides a coverage determination as to whether a particular item or service is covered. A copy of this policy is
available at http://www.cms.hhs.gov/mcd/search.asp. If you do not have Web access, you may contact the contractor
to request a copy of the NCD.”
If denying services furnished after July 1, 2002, use ASC X 12-835 claim adjustment reason code 50, “These are non-
covered services because this is not deemed a ‘medical necessity’ by the payer.”
